When Cauldron Familiar enters, it, Blasting Station and Weapons Manufacturing trigger.
Resolve the Blasting Station trigger, untapping it.
Resolve the Cauldron Familiar trigger, causing each opponent to lose 1 life and you to gain 1 life.
Resolve the Weapons Manufacturing trigger, creating a Munitions artifact token.
Activate Blasting Station by tapping it and sacrificing Cauldron Familiar.
Activate Cauldron Familiar by sacrificing the Munitions, as it is a Food due to Ragost.
The Munitions triggers, dealing 2 damage to any target.
Resolve the Cauldron Familiar ability, returning it from your graveyard to the battlefield.
Repeat from step 2.
This loop turns a simple cat-and-oven dance into a catastrophic artillery strike by blurring the lines between creatures and artifacts. Thanks to Biotransference, your creature spells and permanents—including the ever-returning Cauldron Familiar—count as artifacts, allowing Weapons Manufacturing to flood the board with Munitions tokens every time the Familiar enters. Meanwhile, Ragost, Deft Gastronaut pulls double duty by turning every artifact you control into a Food and giving you the reach to burn opponents down with activated abilities, while Blasting Station provides the sacrificial outlet and untaps itself endlessly to keep the loop self-sustaining.
